Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
VeggieVerve/Livingston Naturals 'Lung & Breathing Cleanse' liquid formula with mullein, nettle, white horehound, osha root, elecampane, peppermint, eucalyptus, turmeric, black seed, and vitamin C. Two problems. First, 'lung cleanse' is unverified_medical_claim — the lungs have mucociliary clearance mechanisms that continuously clear inhaled particles in every healthy person, and there is no oral supplement that meaningfully 'cleanses' the lungs. Real respiratory conditions (COPD, asthma, bronchitis, pneumonia, ILD) are diagnosed by pulmonology workup and treated with evidence-based medications. Substituting an herbal tincture delays treatment. Second, some individual ingredients have modest traditional-use evidence for cough/cold symptomatic relief (mullein, peppermint, eucalyptus have soothing effects), but osha root has documented liver toxicity in some case reports, and the multi-herb blend at undisclosed doses is proprietary_blend_hides_dose. Compound autofail on unverified_medical_claim (lung cleanse framing).
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
